MACHINE FOR FACING NUTS, 800.

SPECIFICATION forming part of Letters Patent No. 711,504, dat d O t b21, 1902.

7 Application filed February 8, 1902. Serial No. 93,185- (No model.) 7

To ctZZ whom it may concern:

, Be it known that I, CHARLES W. JAMES, a citizen of the United States,and a resident of the city and county of Philadelphia, Statespecification.

My invention relates toimprovements in machines for facing nuts or forperforming analogous operations upon blanks or pieces of metal; and theobject of my invention is to furnish a machine by means of which eitheror both the top and bottom faces of a nut may be automatically smoothedor faced or whereby substantially similar operations may beautomatically performed upon other blanks or pieces of metal.

In the accompanying drawings, forming part of this specification, and inwhich similar characters of reference indicate similar parts throughoutthe several'views, Figure 1 is a side elevation of my automaticnut-facing machine; Fig.2, afront elevation of Fig. 1; Fig. 3, a sectionof Fig. l on line A B; Fig. 4, a side elevation of the inner face of oneof the sides of the reciprocating carriage; Fig. 5, a section of Fig. 4on line 0 D.

a a are the end frames of the machine, which carry the guiding-plates bc.

d is a reciprocating carriage preferably constructed in two pieces e f,as best shown in Fig. 3, which is fnrnishedwith passages g h for thenut-blanks, one half of said passages being formed in the piece c, theother half in the piece f. The carriage cl is guided by theguiding-plates b c and is free to move to and fro therein.

11 represents pins, one upon each side of carriage d, to which one endof rods j are pivotally secured, the other ends of said rods beingsecured to cranks or eccentrics on a shaft Z, carried by frame a.

m n are gear-wheels, fast to shaft Z, which gear With gears 0 19, fastto a shaft 7", which carries a pulleys, which is driven by a belt (notshown) from any suitable and convenient source of power. Through therevolutions of pulley s and the intermediate gearing and connections thecarriage d is caused to reciprocate in the guide-plates b c.

t is a tube connected with any suitable hopper, (not shown,) throughwhich the nutblanks are fed down to the passage g in carriage d.

u is a longitudinally-adjustable stationary rod or stop carried by framea, the longituline with the longitudinal axis of the passage 9 and whichis of less cross-sectional area than the passage, so that it can passtherein.

o is a spindle carried by frame a and axially in line with passage g.This spindle is adapted to carry and revolve a tool w, which faces thenut or performs an analogous operation upon the protruding blank carriedby passage g.

l is a longitudinally-adjustable stationary rod or stop carried by framea, which is placed opposite to and which is adapted to enter the passageh in carriage d.

2 is a spindle carried by frame a, which is axially concentric with thepassage h.

3 is a tool carried by spindle 2, adapted to operate uponthe projectingface of a nut or other article carried by passage h.

4 is a basket carried by carriage d, which directs nuts falling frompassage 9 to the passage h.

5 is a shaftcarrying a pulley 6 and pinions 7 8, which gear "with gears9 10, the former fast to the shaft o, the latter fast to shaft Z, whichcarry the revolving facing; or cutting tools.

- The pulleys s 6 being driven by belts in the usual manner, the blanksare fed down through tube t into a .vertical opening 11 in carriage d,which connects with the horizontal passage g therein. When the interiorof tube 25 and opening 11 are in line, the carriage is at the end of itsforward stroke and the rod u is in the position shown in Fig. 1 that is,its outer end is within the passage and is engaging the last blankthereinand closes off the lower end of the opening 11. As the shaft 7crevolves the rodj pushes the carriage backward and advances its rear endtoward the facing or cutting tool w. Just before this tool is reachedthe carriage d has been moved far enough backward to permit the opening11 to clear the end of rod u. When the blankcarried by this openingfallsinto the passage g, forming with the other blanks in this passage andthe rod on a continuous rigid bar,

dinal axis of which is in or substantially in the outer end of the outerblank, which projects somewhat beyond the end of the carriage, isengaged by the revolving tool 20 and is faced or otherwise operatedupon. As the motion of the carriage is reversed by a further revolutionof shaft 70, the forward nut of the line of nuts in passage g is engagedby rod u, and the outer nut, the one that has just been operated upon,is pushed out of passage g and falls into basket or cage 4, whichdirects it to the passage it, into which it is pushed by the rod 1 whenthe carriage is moved backward. When the carriage is moved forward, thenutin the forward end of passage 72 and which projects out beyond theend of the carriage is engaged and faced by the revolving tool 3. Whenthe carriage is again moved backward, this nut is through the line ofnuts in passage 7L and rod 1 pushed out of the passage and falls downand out of the machine.

It will be seen that the operation of the machine is continuous, oneside of one nut being faced upon the completion of the backward strokeof the carriage and the other side of another nut upon the completion ofthe forward stroke of the carriage.

If it be desired to face but one side of the nut, but one passage in thecarriage and one cutting-tool would be used.

As has been intimated, the machine may not only be used for facing nuts,but for performing any other analogous operation upon nut-blanks orother blanks or pieces of metal.

The carriage (Z is preferably formed in two pieces, as shown, for easeof tooling the passages g h, 850. Its lower end runs in guides 12 13,carried on the plate 0, which guides are adjustable by means of screws14:. By setting the guides 12 13 in or out the carriage may be raised orlowered or moved from side to side, so as to bring the center lines ofthe passages g h directly in line with the center line of the spindles'0 and the cutting-tools carried by them. The two parts of the carriage(Z are held together by bolts 15, and by setting up the nuts carried bythese bolts the two sides of the carriage can be brought together, so asto bear tightly against the nuts in the passages g h, preventing anymovement of the nuts when being operated upon by the cutting-tools, butnot holding them so tightly that they cannot be moved by the rods u 1when the carriage is reciprocated. The ends of the passages g h, towhich the nut-blanks are first fed, are sufficiently large in section topermit the easy entrance of the blanks, which are not necessarilygripped by the sides of the passages until they get close to the endsadjacent to the cutting-tools.

The inner ends of the rods to 1 are threaded and screwed into the framesat a. They are both equipped with jam-nuts 16 to hold them in place whenthey have been properly adjusted for the work in hand.

Having thus described my invention, I
